Emergency button for vehicle

Abstract

An emergency button for a vehicle used for emergency rescue when a vehicle accident or an emergency situation occurs has a design structure reflecting a design to prevent an erroneous operation for conforming to governmental regulations, and an intuitive human-machine interface (HMI) to allow a user to easily operate the emergency button and prevent an erroneous operation from being generated. The emergency button includes a case; a cap coupled to an upper portion of the case so as to move up and down during rotation; and a button part which is interfered in a rotation direction and slidably coupled with the cap to be rotated together with the cap, receives elastic support by a spring at a lower side to be movable up and down, and is in contact with the switch for transmitting a call connection signal within the case to transmit a call connection signal.

What is claimed is: 
     
       1. An emergency button for a vehicle, comprising:
 a case in which a switch for transmitting a call connection signal is mounted; 
 a cap coupled to an upper portion of the case in a screw-engagement structure to move up and down during rotation; and 
 a button part which is interfered in a rotation direction and slidably coupled with the cap to be rotated together with the cap, receives elastic support by a spring at a lower side to be movable up and down, and is in contact with the switch for transmitting a call connection signal within the case through a lower surface thereof to transmit a call connection signal, 
 wherein upward movement of the button part is limited by a stopper provided at an upper end of the case by using a latching part having an inclined structure formed along a circumference of an outer peripheral surface, and the button part protrudes from an upper surface of the cap when being rotated in a predetermined direction. 
 
     
     
       2. The emergency button of  claim 1 , wherein an LED and an LED-side contact point are provided at the button part, and a power-side contact point is provided on a wall surface of the case, so that the LED is turned on when both contact points are connected with each other according to the rotation of the button part. 
     
     
       3. The emergency button of  claim 1 , wherein the button part is made of a light emitting material, which allows light to be diffused, so that the entire button part emits light while light is diffused together with the turning on of the LED. 
     
     
       4. The emergency button of  claim 1 , wherein a pad which is capable of turning on the switch by pressing the switch for transmitting a call connection signal protrudes from the bottom surface of the button part. 
     
     
       5. The emergency button of  claim 1 , wherein a character figure part is formed at the button part, and a character figure part hole corresponding to the character figure part of the button part is formed at the cap, so that the character figure part protrudes from the upper surface of the cap when the button part moves up. 
     
     
       6. The emergency button of  claim 1 , wherein a proximity sensor is attached onto the upper surface of the button part, so that an audio guidance or a screen guidance which notifies generation of an emergency situation when a movement of a user is sensed, is provided to a user.
